So, your best answer for the title of the video?
Answer: one. Makes sense right, if title one is chosen.

I guess the people who came up with the phrase “Car Free Day” should look and think again, maybe to the East i.e. China. And, paraphrase it to “No Car Day” if the meaning or what is being put forward is not what has been nicely put into moving picture as above. Well, maybe not just the East, maybe common sense would do here.

As for Bahasa Indonesia, would we still use “Car Free Day” and “Hari Bebas Kendaraan” or “No Car Day” and “Hari Tanpa Kendaraan”?
